Specification of Letters Patent.

Patented July 10', 191W.

Application filed December 9, 1916. Serial No. 136,062.

To alZ whom it may concern:

Be it known that I, FREDERICK E. MEE- HAN, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylva'lii'a, have invented certain new and useful Improvem-ents in Printing-Presses, of which the fol lowing is a specification.

My invention relates to improverne ts in printing presses and particularly to a dis tributer for printing presses adapted to "distribute the ink upon the rollers after the rollers have passed over the chase. The object of my invention is to provide a distributer plate which is movable in a line diagonal to the axis of the rollers; and a further object of my invention is to provide mechanism for reciprocating the distributer plate and a still fnrther object of my invention is to impart an intermittent fmotion to the distributer plate when the rollers are in the raised position and not resting upon the distributor plate.

Referring to the accompanying drawings Figure 1 is a vertical section of a printing press and showing my improved distributer; Fig. 2 is a rear elevation of the printing press, as shown in Fig. 1; Fig. 3 is a plan view of the distributer detached; Fig. 4 is a sectional view on line 4:4: Fig. 3; Fig. 5, is a section on line 55 Fig. 4, showing the eccentric for reciprocating the distributer plate; Fig. 6 is a view similar to Fig. 4:, showing a different means for reciprocating the distributer plate; and Fig. 7. is a section on line 7-7, Fig. 6.

Referring to the drawings in which like reference characters refer to like parts 1, represents the frame of the printing press to which is pivoted the back 2, which is moved upon the shaft 3, into the forward position shown in dotted lines Fig. 1, by the connecting rod 5, and the disk 6, on the shaft 7 mounted in the frame 1.

The rollers 9 are carried by the frame 10, pivoted upon the shaft 12 which is mounted upon the back 2. The rollers 9 move upwardly when the back 2 is moved into the forward position, as shown in dotted lines, and the rollers 9 receive the ink from the disk 15, and when the back moves rearwardly the rollers 9 are moved over the type in the chase 16 and over the distributer plate 18.

The distributer plate 18 is mounted upon the brackets 21 and 22, secured to the frame forming the back 2. The brackets 21 and 22 are provided with jaws 23 and 24, respectively, which jaws embrace the side members of the back 2, to which the brackets are securely held by the set-screws 25. The arms of the brackets are provided with slots 27 and 28, through which pass the bolts 29 and 30, carrying the distributor plate 18. The bolts 29 and 30 are free to move in the slots 27 and 28, formed in the brackets.

The bracket 21 has a shaft 32 rot'atably mounted therein and said shaft has an eccentric 33 secured thereon, which eccentric 33 operates in an aperture 19 formed in the distributer plate 18 and engages the said plate 18; and imparts a reciprocating motion to the same, when the shaft 32 carrying the eccentric "33 is rotated.

Upon the shaft 32 is keyed, "or otherwise secured, a wheel 35, having arms 36, formed thereon, for rotating the same. The arms 36, are adapted to be engaged by a pawl 450, pivoted upon a bracket 41, secured to the main frame 1, of the press.

The pawl 40 is located in such a position that it is in the path of one of the arms 36 on the wheel 35. When the back 2 moves forward, one of the arms 36 of the wheel 35, will strike the pawl 40 and tilt the pawl upon its pivot pin 42. The counter weight 43 on the lower end of the pawl 10, will return the pawl to the vertical position, when the arm 36 of the wheel has passed beyond the pawl. Upon the rearward movement of the back 2 the arm 36 of the wheel will strike the pawl 10 and rotate the wheel, as the pawl 40 is held by the stop pin 44:, on the bracket 41, against rearward movement.

At the time the wheel 35 is engaged by the pawl 40, the ink rollers 9 are in the raised position, as shown in dotted lines Fig. 1, so that the distributer plate 18 is free to move.

The brackets 21 and 22, carrying the distributer plate 18, are secured to the frame so that the slots 27 and 28, formed in the backets, extend parallel with each other and as the said slots in the brackets extend in a diagonal line the distributor plate 18 will have a diagonal movement in relation to the axis of the rollers 9 and the latter will contact with the distributer plate in a new place on each successive movement of the rollers. As the position of the distributer wheel is provided with a platechanges both vertically and horizontally the ink upon the rollers 9 will be a greater movement to the distributer plate than can be conveniently done with the eecentric, shown in Figs. 8 and 4, due to the fact that it is necessary to form the'distributer plate as shown in Fig. 3, with the lower central portion cut away so that the distributer plate'will not strike the pawl when the back 2 is moved forward.

Having thus described my invention I claim and desire to secure by Letters Patent': c

1. In a device of the character described, comprising a printing press having an ink roller, a distributer plate over which said inkroller passes, brackets secured to the printing press and forming guides for the distributor plate extending in a line diagonal to the axis of the ink roller and means for moving the distributer plate in theguides formed by the said brackets.

2. In a device of the character described,

Copies of this patent may be obtained for five cents each, by addressing the mounted upon the frame,

the combination of a frame, a movable back pivotally mounted upon the frame, a distributer plate mounted upon the back, a shaft rotatably mounted, means for imparting motion to the distributer plate from said shaft, a wheel secured on said shaft, a pivoted pawl secured to the frame of the press and adapted to engage the said wheel and move the distributer plate when the said movable back is actuated.

3. In a device of the character described the combination of a frame, a back pivotally brackets secured to the back, a'distributer plate slidably mounted upon said brackets, a shaft rotatably mounted upon one of said brackets, a wheel upon said shaft, means for imparting motion from the shaft to the distributer plate, a pawl, a bracket on which the pawl is pivotally mounted, a stop upon said bracket to limit the movement of the pawl and projections upon said wheel adapted to be engaged by the pawl and rotate the wheel.

In testimony whereof I aflix my signature in. the presence of two witnesses.
